Exception duing initialisation of linkd

Description

This one reared it's head as I was doing a test run with the current code for linkd:

2011-12-07 03:14:39,609 INFO [LinkdScheduler-3 Pool-fiber0] HibernateEventWriter: processIpNetToMediaTable: Setting OnmsAtInterface MAC address to 001ae3719541 but it used to be '' (IP Address = 172.31.255.2, ifIndex = 100)

This is strange... the "No session" message means that no Spring transaction is wrapping the current operation and the transaction is necessary for the current operation. However, it also looks like there is a transaction since the code is executing inside a TransactionTemplate.execute() block. I would retry this code with Antonio's latest changes, he has made lots of updates to Linkd since devjam in 1.11.

If 1.11 still fails, then please reopen the bug.
